Reviews Ultrasonic Sensor Module

Mini Motion/Daylight Ceiling Sensor-DIM Kit

  • Combines passive infrared and ultrasonic technology providing the most accurate motion ceiling sensor possible. The ultrasonic sensor can defect fine movements such as typing, and flipping book pages.
  • The ceiling sensor is designed to be mounted about 8-10 feet off the ground. The implementation of two sensing technologies in each unit helps to avoid false triggering while still accurately sensing motion.
  • 6 different trigger modes that use a combination of both PIR and ultrasonic sensor. Has adjustable time delays via dip switch (5 sec - 30 min).
  • Multi-level Coverage, up to 1, 600 ft² PIR coverage and up to 1000 ft² ultrasonic coverage.
  • UL/ CUL Listed. Operating temperature (32 – 131°F).
  • California Title 20 and 24 compliant. 120/277 VAC, 1/4HP-120VAC.
